6 Claims. H (01. 132--36.1)

This invention relates to improvements in accessories used in connectionwith the permanent waving of hair and pertains particularly to animproved scalp protector or spacer. In the'operation ofpermanent waving,the hair is secured between two jaw members which are placed against thescalp and these jaw members are secured firmly together and. support arotatable cylinder on which the hair is wound. In the device at presentin use, the separable ends of ported that it is necessary for theoperator to g,

employ both hands in taking out the roller.

The present invention has for its primary object to provide an improvedcoupling means between the hair gripping jaws whereby the said jaws ofthespacer may be readily separated with one hand and an additionalfeature of the present device resides inthe novel construction of thesupporting means for one end of the roller whereby such supporting meansreleases the roller automatically when the jaws are separated.

Another object of the invention is 'to provide an I improved spacer orhair securing clamp wherein the operating means for. securing the jawsin clamped relation or for releasing the jaws, is disposed at one sideof the spacer in such a manner that the operator may hold the spacerbetween a thumb and finger of the hand and employ. another finger of thesame hand to release the jaws and shift them into separated position, inwhich position the roller on which the .hair is' wound will beautomatically released. The invention will be best'understood from aconsideration of the following detailed description taken in connectionwith the accompanying drawing forming part of this specification, withthe understanding, however, that the invention is not to be confined toany strict conformity with the showing ofthe drawings but may be changedor modified .so long as such changes or modifications mark no materialdeparture from the salientieatures of the invention as expressed intheappended claims.

In the drawing:

'Fig. 1 is a, view in top'plan of the protector embodying the presentinvention;

"Fig. 2 is a view in top plan of the device with the jaws separated andcylinder removed;

Fig. 3 is a view in end elevation of the device with a portion brokenaway;

Fig. 4 is an end view illustrating the separable trunnion bearing; and

Fig. 5 is a side view of the device at the pivoted ends of the jaws.

Referring now more particularly to the drawing, the numeral I generallydesignates the spacer device or clamp for the hair while the numeral 2designates the cylinder which is rotatably mounted upon the spacer andupon which the hair is wound.

The spacer l comprises the two usual jaw members 3 and 4, each of whichconsists of a flat strip of metal which has one edge and the top andbottom faces thereof covered by a rubber guard 5. I

In accordance with the present invention, one of the jaw members, forexample, the jaw 3, is formed at one end with the laterally extendingarm ,6, while the opposite jaw has the end adjacent the arm 6 laterallyand obliquely extended to form the lever arm l. The end of the arm ii ofthe jaw 3'is pivotally attached to the jaw 4 at the inner endof thelever arm 1, as indicated at-S.

The jaws '3- and 4 at their opposite ends have upturned portions 9 andI0, respectively, which, when the jaws are in hairgripping relation, arebrought into edge opposed relation, as shown in Figure 3, and as is alsoshown in this figure, one of these upturned portions is recessed at itstop and adjacent the inner edge thereof to form a bearing H, while theadjacent or opposed upturned portion It] extends across and forms oneside of the bearing. As is also clearly shown in this figure, one of theupstanding end portions is provided with a tongue [2 which extends intoa receivingslot I3 in the opposing portion, thus forming aninter-locking connection between the free ends of the jaws which, whenthe jaws are closed, holds them in alined relation. One of thejaw'members, here illustrated as jaw 3, has pivotally attached theretoat the end remote from the arm 6, one end of a lever bar M, the otherend of this bar being formed to provide the upstanding finger piece [5.Pivotally attached to the lever bar l4 adjacentthe free end thereof isone end of a link 16, the other end of this link being pivotallyconnected, as indicated at H, to the free end of the lever arm I.

When the jaws 3 and 4 are in alined relation, the arm 1 of the jaw4,which jaw may be referred to as the movable jaw, extends across theadjacent end of the other or fixed jaw 3 and away from the latter, andthe bar and link M-IB are in parallel relation with one another bar andlink into this parallel relation, the jaws are firmly secured togetherand the upturned end portions 9 and II! are in the interlocked relationshown in Figure 3.

Formed integral with the edge of the arm 8 remote from the jaw 3, is anupstanding flange [3, the top edge of which is provided with a bearingnbtch Hi. This bearing notch is alined longi- 'tudinally of the devicewith the bearing recess ll, when the jaws are in gripping relation, andthe bearing notch and recess are designed toreceive the trunnion-likeends 20 and 2i, respectively, of the cylinder 2. This cylinder is of theusual construction in that it comprises the elongated jaw portion 22which is enlarged at each end and at one end is formed to provide theencircling ratchet 23 which is designed to be engaged by the spring pawl24 which is supported upon one of the jaw members, preferably themovable jaw 4, as shown. The trunnion 2B which engages in the bearingnotch 19, has formed integral therewith the key head 25, by which theturning of the cylinder is facilitated, and the cylinder also carriesthe usual pivotally attached finger 26, which secures the ends of thehair against the cylinder when starting the operation of winding thehair on the cylinder.

From the foregoing, it'will be readily apparent that in the presentspacer device or scalp protector, the opening orclosing, action of thelaws may be readily accomplished by the use of one hand and that whenthe jaws are opened by shifting the lever bar outwardly away from theadjacent body so as to effect the swinging ofthe other or movable jaw,away from the body 3, the bearing support for the end of the cylinderwhich is engaged by the spring pawl 24, will be opened or separated sothat said end of the cylinder will be separated from the spring pawl andthe cylinder may be lifted out without requiring that the operatormanipulate the spring pawl to disengage it from the ratchet-23.

As previously stated, the devices which are at present in use are soconstructed that both hands must be employed for removing the springpawl engaged end of the cylinder as it is necessary to hold the cylinderwith one hand and force the spring pawl free from the cylinder with theother hand. With the present device, this is not necessary, as the mereseparation of the free or unconnected ends of the jaws simultaneouslydisengages the cylinder from the spring pawl.

The lever mechanism connecting the jaws together and consisting of thearm 6, bar l4 and link I6, is so designed that when the jaws are inclosed position, they will be firmlysecured together as the link I8 andthe lever bar M are then in aligned relation and are exerting themaximum force against the free end of the lever arm 1 necessary to holdthe jaws tightly together in gripping relation. 7
